Daniel Ivancho (March 30, 1908–August 2, 1972) was the third bishop of the Byzantine Catholic Metropolitan Church of Pittsburgh, the American branch of the Ruthenian Catholic Church.
Born on March 30, 1908 in Yasinia, Máramaros, Austria-Hungary, he emigrated at the age of eight to the United States and settled in Cleveland, Ohio with his widowed mother. He graduated from St. Ignatius High School (Cleveland) in Cleveland, Ohio in 1926. He graduated from St. Procopius College in Lisle, Illinois and completed his seminary training in Rome, Italy. Due to illness, he transferred to Uzhhorod Theological Seminary where he completed his studies. On September 30, 1934, Bishop Basil Takach ordained him to the priesthood and he served in parish assignments.
When Bishop Takach was diagnosed with terminal cancer in the 1940s, a request was made to the Holy See for the appointment of an auxiliary bishop. Monsignor George Michaylo and Father Stephen Gulovich were perceived to be leading candidates, but the Vatican announced the appointment of Ivancho, a dark horse. The 1946 official decree declared his status to be a "Coadjutor Bishop", mandating that he would automatically become Bishop Takach's successor.
He was ordained as the first-ever Coadjutor Bishop of the Greek Catholic Exarchate of Pittsburgh on November 5, 1946. In order to accommodate the crowds, the ceremony was held at the Cathedral of Saint Paul of the Roman Catholic Diocese of Pittsburgh in the Oakland district. Byzantine and Roman Catholic bishops and clergy attended, as did the Empress Zita and other members of the Imperial Habsburg family of the former Austro-Hungarian Empire. Monsignor Fulton J. Sheen was the homilist for the ordination.
